No wonder!
If that's really the case, then the legendary vast Beastman Empire that spanned the entire continent might indeed have existed.
The Pure-bloods cutting off contact between the Royal Court and the myriad Beastman Tribes outside is probably to prevent further provoking the humans.
After all, with such gloriously unmatched feats of ruling the continent in the past, if the Pure-bloods were to unite the tens of millions of Beastmen within the Kawa Great Forest, the Beastman Kingdom they establish would surely become the target of hostility from the majority of human royal palaces.
Secretly supporting the establishment of super tribes like the Blood Claw Tribe at the border and frequently clashing with humans is probably another means of diverting attention.
